Abstract:

Objective To investigate the current status of subsyndromal delirium in elderly patients after hip arthroplasty. Methods One hundred and two patients with hip arthroplasty who were admitted to the orthopaedic ward of a tertiary first-class hospital in Zhengzhou City were selected from May to December 2021. The Age-Adjusted Charlson Comorbidity Index（ACCI） and the Chinese version of the 3-minute Diagnostic Interview for CAM were investigated. Meanwhile，the fracture site，preoperative fasting and water prohibition time，preoperative bed rest time，and the duration of surgery were recorded. Results Seventy-five patients developed subsyndromal delirium after operation. Compared with the non-subdelirium group，the subdelirium group had a greater proportion of women，higher ACCI，and longer preoperative bed rest，fasting，and water deprivation（all P<0.05）. Conclusion The incidence of subsyndromal delirium in elderly patients after hip arthroplasty is high，and medical staffs should pay attention to the female patients，and patients with high ACCI，preoperative bed rest，preoperative fasting，and prolonged water deprivation.
